To all whom itmay concern:

Be it known that I, Janis-Janos song DEREGGER, a citizen of the Swiss Republic, residing at Arbon, near St. Gallen, Switzerland, have invented a new and useful Machine for the Automatic Insertion of Bobbins in the Shuttles of Embroidering-Machines or the Like, (for. which I applied for a patent in Germany on the 26th of May, 1898; in Switzerland on the 28th ofMay, 1898; in Austria on the 10th ofJune, 1898; in France on theth of June, 1898, and in Great Britain onthe 18th, following is a of June, 1898,) of which the specification.

This invention has relation to a machine for mechanically inserting bobbins'into. shuttles, and more particularly for insertingflbobr.

bins into the shuttles used in embroideringr machines in such manner that said shuttles when they leave the machine are ready. for insertion into the shuttle-carrier of embroidcry-machines. I I I The invention consists, broadly speaking, in feeding devices operating to automatically and periodically feed the empty closed shuttles to a suitable holder, and in mechanisms for opening the shuttles, inserting a bobbin, closthe machine, the shuttle-feed trough being removed and showing the guide-plate for the shuttle-ejector pins. Fig. 3 is a fragmentary sectional front View showing a part of, the shuttle-feed trough, the shuttle-ejector, the means for actuating the same, the shuttleholder, and its carrier-slide. Fig. 4is a plan view of Fig. 3, the shuttle-feed trough being partly broken away; Fig. 5 is 'a cross-section on line y y of Fig. 3, looking toward the right. Fig. 6 is a-fragmentary front elevation showing the shuttle-holder, i its carrier, and the spring.forfclosingthe holder. Fig. 7 isa top plan viewof.

Fig. 27 is also a fragmentary plan view showing the position of the thread-holder after having drawn the bobbin-thread under shuttle tension-spring and under a spring-clip on the shuttle-holder, holding the thread taut and ready to be seized by the threading-hook and threaded through the thread-opening in the shuttle-wall. Fig. 28 is a longitudinal sectional view of Fig. 27. Fig. 29 is a similar fragmentary view showing the threadinghook in its position after drawing the bobbinthread through the thread -openin g in the shuttle. detail illustrating the auxiliary shuttle-closer preferably used to insure the engagementof the shuttle-cover with its retaining device. Fig. 31 is a fragmentary view, parts being shown in dotted lines, illustrating the means for ejecting the filled shuttle from its holder; and Fig. 32 is a fragmentary elevation showing the means for revolving the bobbin-carrier.

On a suitable frame, from which the operative mechanisms are supported, are secured two gpide-rails B having a guide-groove in their proximate faces, in which grooves the shuttle-holder slide or carrier B has motion. To the guide-rails B are secured brackets from which the lower end of an upwardly-inclined shuttle-feed trough A is secured and in which the shuttles S are placed with their longitudinal axes transversely of the trough and with their covers closed down, the width of the trough being such as to allow the shuttles therein to freely slide along the open delivery end.

Inasmuch as one shuttle after another is to be supplied with a bobbin, said shuttles must be fed intermittingly from the trough to the mechanism through which the bobbins are introduced into the shuttles, and to prevent the shuttles from sliding out of the trough the lower end of its cover is slotted and has secured thereto a flat spring a whose free end lies in the path of the lowermost shuttle and prevents it from dropping out of the trough, Figs. 1, 3, 4, and 11.

The shuttles S are successively and intermittingly ejected from the trough by means Fig. 30 is a fragmentary sectional of ejecting appliances A, consisting of a spindle a, journaled in bearings secured to the guide-rails B said spindle being provided with two radial arms a and a To the radial arm a is hinged a plate a, from which project two ejector pins or fingers a, guided in a suitablyapertured plate of, secured to the bottom of the shuttle-feed trough A at its delivery end. The plane of motion of the ejector-fingers relatively to the shuttle at the delivery end of the trough is such that said fingers when moved into the trough through suitable openings in its bottom will impinge upon the shuttle, on the left side thereof, sufficiently close to its vertical axis to eject said shuttle from the trough, said shuttles having a more or less conical form in cross-section. The second radial arm or projects into the path of two abutments a and a in the form of angle-plates, secured to the slide B at suit able distances apart, Figs. 2, 3, and 4, so that when said slide reaches the limit of its movement from right to left, at which time the holder for the shuttles will be below the delivery end of the feed-trough A, the said radial arm a comes in contact with abutments a thereby rocking the spindle a to move the ejector-fingers a. into said trough, thereby ejecting the lowermost shuttle S, which drops into the shuttle-holder B cover upward. When, on'the contrary, the slide 13 moves from left to right to carry the shuttle-holder, with its shuttle, tothe mechanism for int-1'0. ducing a bobbin, the radial arm a comes in contact with the abutment ahthereby rocking the spindle a in a reverse direction and retracting the ejector-fingers a from the trough A, allowing the next succeeding shuttle to slide down to the delivery end of said trough, where it will be held by the spring at until ejected.

The abutment a may be dispensed with and the ejector allowed to move out of the trough by gravity. I prefer, however, to move it positively in order to insure its being retracted from the trough A.

In practice I prefer to secure to the front bearing for the ejector-spindle a a flat guardspring or more or less resilient plate a projecting from said bearing toward the right thereof a sufficient distance to close the front end of the open shuttle-holder B when it lies under the delivery end of the feed-trough A to prevent the shuttle dropping into said holder from accidentally sliding too far to- Ward the front or partly out of the front end on iever Z2 being held in contact-with. the cam e by a spring I), secured to the afore said block on the slide B and to a frame part. (See also Fig. 1.)

The shuttle-holder B is carried by the slide B at or near its right-hand end, and referring more particularly to Figs. 1 to 4 and 6 to 10, and, as shown, said holder consists of twoparts, one, b secured to the slide B and provided with perforated lugs or ears I), in which is loosely mounted a hinge-pintle b, the other part, I), being likewise provided with perforated lugs or ears-b throughwhich the hingepintle 1) passes loosely. The two parts of the shuttle-holder are so constructed as to form between them a seat suitable to the accommodation of the shuttlesand to properly hold the same. The pintle b has secured to its rear end, outside of the holder 13, a radial arm 5 and about midway of its ends, within the holder, a cam 6 The radial arm 5' in its normal position projects vertically above the pintle b and the angular relation between arm b and cam 17 is such that when said arm b is partly revolved the greater diameter of cam b will lie in a vertical plane above the axis of the pintle b. To the front end of pintle b is pivoted a two-armed lever 6 whose shorter left arm is pivoted to the hinged part b of the holder B, while its longer right arm has a laterally-projecting pin carrying a roller 6 in the path of the upper edge of a plate 19 secured to the front face of the forward one of the two guide-rails B in which the slide Bhas motion, which upper edge of plate I)? is curvilinear and inclines toward the right. A fiat spring b is secured to the slide B, (see Figs. 1 and 2,) whose free endbears against the under side of the hinged part bof the holder 13 and holds said part Z) in its closed position. When, however, the slide moves toward the left and the roller'l) rides up the inclined track on plate b the lever b is tilted and moves the said part b away from part b against the stress of spring h, or, in other words, opens the shuttle-holder B for the reception of a shuttle. The relative arrangement of the parts is such that the shuttleholder will be fully open when the slide B has reached the limit of its motion to the left, at which time the said holder will be below the delivery end of the shuttle feed-trough A and the ejector Awill be actuated to eject a shuttle from the trough, as above described. Of course when the slideB moves toward the right and the roller b rides down the incline of plate I) the lever b is released, leaving the spring b free to again close the shuttleholder B.

On the rear face of the fixed part b of the shuttle-holder B is secured a finger b, that projects toward the hinged part b to hold the shuttle against rearward displacement, and I said part I) has an opening 9 and on the upper face at its rearend a thread guide-lip b for purposes presently to be described. When a shuttle has been fed to the holder 13 and the-latter has moved away from-the feed-trough A a sufficient distance to effect the release of lever N, as above described, and permit the spring I) to close the hinged part b of said holder upon the shuttle, the latter will be firml y gripped and held against lateral as well as endwise movement. It is, however, also necessary to the subsequent operations of the mechanisms wherebya bobbin is introduced into the shuttle that the latter be firmly seated in the holder and held against vertical displacement. is held against vertical displacement by the gripping actionthereon of the hinged part b ef.the holder B, and it is firmly seated therein by the cam b moved under it, when said holder moves toward the right and when the roller b on'lever b is about to reach the righthand end of its track on plate b that is to say, when said lever is about to be released to enable the spring I) to close the part b of the holder upon the shuttle therein. To this end I provide a two-armed lever 0 fnlcru med upon the arm of abracket secured to the rear one of the two guide-rails B, the fulcrum-pin c of the lever projecting rearwardly and having secu red thereto a sleeve, or provided with a boss 0 Fig. 31, having two flat faces against which bears the free end of a spring 0 also secured to the aforesaid bracket. (See Fig. 2.) The left-hand arm of the lever c has a downwardly-projecting arcuate extension 0 while the right-hand arm 0 is bent downwardly and has aconvex under face, one of said arms projecting at all times into the path of the aforementioned cam b on the pintle b of the shuttle-holder B. The normal position of the lever c isshown in dotted lines in Fig. 11, its arcuate extension 0 raised out of the path of the radial arm I) and its arm 0 in the path of said radial arm. As the slide B and The shuttle shuttle-holder B move toward the right and when the roller 11 on lever b? has nearly reached the rightend of its track on plate b the arm I) impinges upon the right arm a of lever 0 and as the latter is yieldingly held against rotation by its spring 0 both the arm b and lever will be rotated, and thereby the pintle b suiiiciently to turn the cam b so that its greater half-diameter will lie above said pintle, said cam then supporting the shuttle S, Fig. 10, while the lever c is tilted into the position shown in full lines in Fig. 11 and held in that position by thespringc,

the downward motion of the arcnate exten- I sion c of said lever beinglimited by the shuttle ejector rod R, hereinafter to be referred to. When the slide B again moves toward the left, the radial arm 19' impinges upon the innerface of extension 0 of lever 0 whereby said lever, the radial arm b and cam 79 are returned to their described norl was usual, in a kerf or notch in the shuttle or is locked to the latter in any well-known manner and has in its right-hand edge, near the shuttle-nose, a recess d and forward of the same an oblique thread-slot extending from said edge rearwardly toward the left-hand edge close to the free end of a tension-sprin g d", secured to said cover, the left-hand edge of the latter being notched or recessed at d",

while in the left-hand wall of the shuttle is formed a thread eye or slot (l in line with notch cl and substantially at right angles to the longitudinal axis of said shuttle, forthe passage of the bobbin-thread. (See Figs. 26 to 29, inclusive.) The construction of the shuttle is, however, more clearly shown and more fully described in my application for patent, Serial No. 686,723, filed July 23, 1898, the object of this construction being made apparent hereinafter.

As heretofore stated, the shuttles S are fed to the holderB with their covers closed down, so that before a bobbin can be introduced it is necessary that the shuttle cover (1 be opened. This is effected through the medium of the following instrun'ientalities, reference being more particularly had to Figs. 2 and 12 to 16, inclusive: On the cam-shaft w, heretofore referred to, is secured an irregularly-faced cam c, adapted to impart the proper movements to a radial arm 7L2, secured to a rock-shaft 10 said radial arm carrying a roller h held in contact with said cam by a spring 71;, connected with the radial arm and with the framing of the machine. On shaft 10 is secured a lever h, whose outer end is enlarged and forked, the branches of the fork being provided with bearings for the cover-opening rod H, that carries a sleeve h between said branches of the fork. At its inner end the rod H has a radial arm or nose It and the sleeve 1 has two radial pins 71 h diametrically opposite each other, the pin h being connected with lever h by a spring h that holds the opener-rod H with its nose It turned downwardly at an angle, Figs. 13 and 15, said nose h being wedge-shaped. From the front face of lever 72 projects a lug or car W, to which is secured avertical pivotpin, on which is pivoted a two-armed lever H, whose longer right-hand arm its is forked at its outer end and straddles the rod H between two collars 7L0 thereon. The shorter left-hand arm h of the lever H terminates in a stud that projects into an inclined slot having at its lower end a depression or recess, Fig. 14, said slot being formed in the vertical arm of a bracket h secured to a frame memher. The rod H occupies a position on the right of the shuttle feed-trough A and between the shuttle-ejector rod R and the appliances for introducing a bobbin into the shuttle.

The cam-shaft w revolves continuously during the operation of the machine, and the cams c and e are of such configuration that when the slide B is moving toward the right and the shuttle-holder B has reached a point under the rod 11 to enablethe nose It thereof to enter the notch or recess (1 in the shuttlecover the further movement of the slide is interrupted, while the lever h is moved downwardly, thereby inserting the nose h of rod H into recess or notch d in the shuttle-cover d, the said nose impinging upon the righthand wall of the shuttle. Immediately thereafter the slide B is moved toward the left, but only a sufficient distance to cause the wall of the shuttle to act upon the nose 7b of the opener-rod H and turn the same against the stress of spring it, so as to move said nose under the shuttle-cover cl, Fig. 16. The slide B again remains stationary, while the lever 7; begins its upward swing, thereby lifting the shuttle-cover. At the same time the slot in the bracket-arm it causes the arm 7&5 of lever H to swinginwardly, thereby mov ing the rod H in the same direction while said rod is being lifted by the lever h until the latter has reached the limit of its upward swing, as shown in dotted lines in Fig. 12, when the arm 7L5 of lever H and the shuttleopener H will also have reached the limit of their inward movement, as shown in dotted lines in Fig. 13, the shuttle-cover (Z being thereby completely thrown up or into a vertical position. The slide 13 now continues its motion to the right, while the levers h and H and the shuttle-opener H move back to their normal positions, ready for the next operation, which takes place after 'the insertion of a bobbin into the shuttle, the closure of the shuttle-cover and the threading of the bobbin-thread through the thread-eye of said shuttle, the ejection of the latter from its holder, and the return of the shuttle-holder from the feed-trough A with an empty shuttle. To the under side of the lever h is secured a flat spring h", and when the rod H is turned, as above described, from the position Fig. 15, into its operative position, Fig. 16, against the stress of its spring 71 the radial pin h comes in contact with the spring 7L9, and as said pin moves over its dead-center toward the left the spring h, acting thereon, assists in turning the rod H into its said operative position and locks said rod against the action of the spring h In order that the last-named spring may turn the rod H back to its normal position, I provide an abutment in the form of a vertical arm 7t, whose upper end it is bent at right angles and lies in the path of the free end of the spring h which projects beyond the sleeve it, so that when the lever 7L and rod H are aboutto reach the limit of their upward movement the spring it" will come in contact with the bent part it of arm 71, and will be drawn out of contact with the radial pin 71 thereby permitting spring h to turn the rod H back into its normal position. The cover 01 of the shuttle having been opened, as described, the slide B continues its motion toward the right.

111 suitable bearings on the main frame is secured a shaft m, on which is looselymounted the bobbin-carrier, consisting of a disk 'or wheel M, in the rim of which, close to its periphery and parallel with its axis of rotation, are formed a series of closely-arranged but equidistant holes m for the reception of bobbins B Referring more particularly to Figs. 1, 2, 18, 19, and 32, there is in front of the bobbincarrier a plate or receiving-table 0, that projects across the track-rails B and said bobbin-carrier receives a periodical step-by-step or progressive rotation from right to left, as shown by the arrow, Fig. 18, through the following mechanism. v

To the hub of the carrier M, on its rear side,

is secured a ratchetwheel m having a number of teeth equal to the number of bobbinseats m in the carrier, a pawl at the end of a long pawl-arm m being held in engagement with said teeth by a spring we, Fig.32, there being a second pawl m held in engagement with the ratchet-teeth bya spring (shown in dotted lines in Fig. 32) to prevent backward rotation. The pawl-lever 'm is pivoted to a lever at, having rocking motion on a shaft .10 hereinbefore referred to, and being rocked by a cam e on cam-shaft 10, said lever hav-' ing a laterally-projectin g pin carrying a roller mflheld in contact with said cam e by a spring in connected with the lever and with the machine-frame, Figs. 1 and 2. The constructionof the cam or eccentric e is such as to impart to the rock-lever 'm a periodical rocking motion to revolve the bobbin-carrier M, through the pawl-lever m, a distance equal to that between two teeth on ratchetwheel m and equal to that between two bobonto the receiving-table 0, said ejector being guided in asleeve n, supported from the machine-frame, the rear end of the ejector N being pivoted to the upper end of a lever n, loose on a shaft to, arranged longitudinally of the machine, said lever 02 having a laterally-projecting pin carrying a roller n held in contact with the periphery of a cam e by a spring of, connected with the lever and the machine-frame, said eccentric being secured to a shaft 10 parallel with shaft (r above the same, Fig. 2.

lVhen the slide B has reached the limitof its motion to the right, with the shuttle holderB close to the left edge of the receiving- 'table 0 and the shuttle-cover wide open, the bobbin l3 previously ejected from carrier M and lying on table 0 is transferred from the lattcrto the shuttle. I

The bobbins B are inserted into their seats in the carrier M with the loose thread end forwardly, so that when a bobbin istransferredto a shuttle the thread end will be at the forward .end or nose of said shuttle, and

and 17 to 20.

Aslide O has motion in the guide-railsB on the right of the receiving-table o, and from the under side of said slide projects a lug or arm 0, to which is pivoted one end of a connecting-rod 0 Fig. 18, whose opposite end is pivoted to arock-lever 0 on shaft 10 said lever carrying a roller 0 in contact with a suitable cam c on cam-shaft 10', said roller being held in contact with saidcam by a spring 0 secured to the lever and to a frame part, Figs. 2 and 18 whereby'the required to-and-fro movements are imparted to the slide 0. A presser-lever E is loosely mounted on a stud or pin f, projecting forwardly from the vertical arm f of a bracket on the slide 0, and a spring f, secured to, said stud or its support and to the hub or bearing of the le- Qver, tends to draw its left or pressure arm downwardly, while its right tapered arm is held against such motion by a roller f when the lever is in a given position relatively to said roller, which latter is j ournaled on a stud f, adjustable vertically in a slot formed in the vertical arm of a bracket f rising from the-rear one of the two guide-rails B for the slides B and O. The presser-lever E is held in its normal position with is presser-arm elevated, Fig. 1, when the slide 0 is in its normal position or at the limit of its motion toward the right. As the slide 0 moves to the left the tapered right arm of lever E slides along therollerf causing the left or presser arm of said lever tomove down under the action of its spring f and as the slide 0 is about to reach the limit of its movement to the'left the said presser-arm will lie upon the bobbin B on the receiving-table o andv hold the same firmly, the thread end of the bobbin being then held by thread-clamp K.

On the aforesaid stud f is loosely mounted a push-bar E, the forward end of which is T- shaped, forming a cross-head, and between the diverging arms f of said head is a groove 01 channel for the reception of the presser-lever E, the length of the left or presser arm of said lever relatively to that of the pushbar being such that when lever E is depressed, as above described, to hold a bobbin the crosshead of the push-bar E will lie immediately G ceasoe behind such bobbin, ready to push the same over the receiving-table into the open shutg the push-bar E is secured a guide-fingerf for purposes presently to be explained.

It will readily be seen that by means of the devices E and E the bobbin is thrust or rolled into the shuttle with certaintyand in a proper manner-that is to say, with the longitudinal axis of the bobbin in the plane of the longitudinal axis of the shuttle, and this is made more certain because the height of the shuttlcholder is such that its upper face is flush with the upper face of the receiving-table 0, or substantially so, and because at the moment when the bobbin is moved over the table into the shuttle its holder is in contact with said table.

The thread-clamp K, Figs. 2, 17, 18, 19, 20, and 23, between the jaws of which the bobbinthread end passes when a bobbin is ejected onto table 0, is composed of two jaws it 70 pivoted together shear-like, and from the outer or nip end of the ciamping-jaws project lips k and it, respectively, whose proximate faces are convex, as more clearly shown in Fig. 23. The pivot-pin of the thread-clamp K, which may have its inner end screw-th readed, is screwed or otherwise secured to a swivelhead 70, the swivel-pin of which has its bearing in the vertical arm of a bracket 7e on which vertical arm are formed twoshoulders or abutments 24:, and to said swivel-pin between said shoulders is secured a radial screwpin or screw 25, that serves to limit the rotation of the swivel-head in either direction, as more clearly shown in Fig. 20. The proximate faces or edges of the clamp-jaws 7t k are beveled at their rear or left end, so as to diverge rearwardly and form an acute-angled recess between them when the jaws are closed, and immediatelyin rear of their pivotpin a similar but smaller recess is formed, merging into a polygonal opening 26, formed by recessed portions in the proximate faces or edges of the jaws.

To the swivel-head 70 is secured an arm 70 that projects toward the left and carries at its end a pin or stud it which projects into a longitudinal slot 7e formed in an angle-plate 70 secured to a vertical bracket=arm on the rear one of the two guide-rails B said plate projecting over the slide 0, as shown in Figs. 2, 17, and 19. The right-hand portion of the slot 75 lies in a plane in rear of the left-hand portion of said slot for purposes hereinafter to be described, the twoparts of said slot being connected by a diagonal portion.

To the front face of the forward one of the guide-rails B is secured a bracket 29, in the upper end of which is swiveled a clam p-opener 70 having a prismatic block 27 in the path of the left end of the clamp-jaws k k a'spring 7& on the swivel-pin of. the opener and secu red thereto and to its bracket, respectively, tending to hold the block .27 in the path of said clamp-jaws, its rotation from left to right under the stress of its spring being limited by a pin 28, projecting from the bracket 29. (See Figs. 17, 19, and 20.)

In its normal position the axis of the pin 75 of the swivel-head 7a, to which the clamp K is pivoted, intersects the axis of the pin 7*, on which the presser-lever E and pushbar E are mounted. The clamp-jaws it 7.: are held normally closed by springs F06, and the left or clamping portion of said jaws projects' some distance beyond the presser-lever E and push-bar E, so that the nip end of said jaws may lie in the path of the bobbinthread end as the bobbin is being ejected from the carrier M. In Fig. 17 these parts are shown in their relative positions ready for operation, the presser-lever E in its elevatecl position, Figs. 1 and 18, the cross-head ff on the push-bar E on receiving-table 0011 the left of the channel 0*, containing the bobbin B the jaws 7t" and k of the thread-clamp K closed upon the loose end of the bobbinthread, the prismatic clamp-opener 27 in the recess 26 betweenthe left arms of said clampjaws, and the pin 7t on arm it of swiveldiead Win the rear end of slot 10 of plate ltithe slide 0 moving toward the left. As hereinbefore explained, during this movement of the slide 0 the presser-lever E is depressed upon the bobbin B ,which latter is then pushed toward the left out of its channel 0 in the receivingplate 0 and into the .open shuttle. At the IOQ same time the pin 76 passes from the left por- Fig. 19, drawing the bobbin thread along.

At the same time the cover 61 of the shuttle is closed down, and the mechanism whereby the shuttle-thread is drawn under the tension-spring d on the cover d of the shuttle and then through the thread-eyein the shuttle-wall set in operation, after which the slides 13 and O recede-from each other, during which movements the shuttle is ejected from its holder and the clamp K opened ready to take hold of the thread end of the next bobbin ejected from the carrier M. After the transfer of the-bobbin into the shuttle the slide 0 moves back to the right, the pin 70 on arm 70 moving from right portion of slot 70 into the left portion thereof, thereby swinging the clamp K back into its normal position. Immediately thereafter the clampopener 27 acts upon the inclined faces at the rear end of the clamp-jaws 7t 76*, which form the recess 76X, thereby opening the clamp,

ceases r which now lies in position to receive the thread end of a bobbin, which at thismoment is ejected from the carrier M, the slide 0 still moving to the left, whereby the clamp-opener passes into recess 26 between the clam pjaws, the clamp closing upon the bobbin-thread under the action of the springs During the described movement of slide O' the roller f acting upon the tapering tail of presserlever E, lifts its presser-arnnas above described, while the push-bar E again lies on receiving-table 0 on the right of groove or channel o i. e., the parts have been returned into their normal position, Figs. 17 and 18. As the slide 0 again moves to the left the swivel-head k is turned from right to left against the stress of its spring 167 out of the recess 26 about the time the clamp K commences to swing outwardly, as above described.

The cover (Z of the shuttle is closed down through the medium of the following instrumentalities. A bar P, which carries at its forward end a roller p, has to-and-fro motion crosswise'of the machine in the line of the shuttle when the latter lies in contact with the receiving-table 0, the said bar havingits opposite ends suitably bent to perform its work, Fig.'2l. Near its rear end the bar P is guided in the fork of an arm 19, in which is journaled a roller pi whereby the forward end of said bar is depressed as its upwardlybeut rear portion 19 moves under said roller, thereby closing down the shuttle-cover, the curvature of the bent portion 19 being such that as the bar P moves forward its downwardly-bent roller end is gradually depressed to close the shuttle-cover. The downwardlybent rear end of the push-bar P is pivoted to a lever 19 on the longitudinal shaft 10 hereinbefore referred to, said lever carrying a roller 19', held in contact with a cam e on the longitudinal cam shaft 10 by a spring 19, Fig. 2, secured to the lever and a frame portion, respectively. As the bobbin is pushed by the presser-lever E and the push-bar E into the shuttle the shuttle-closer bar P moves forward, its roller 19 impinging upon the shuttle-cover d, and as the downwardly-bent forward end of the bar is gradually depressed the said shuttle-cover is gradually closed, the

closer-bar'receding to its normal position, .Fig. 2, under the action of its cam c imme- These K, drawn into the oblique slot d in the shuttile-cover, Fig. 27, then under the tensionclamp.

through the eye d in the side wall of the shuttle.

In order to absolutely prevent endwise displacement of the shuttle in its holder while the shuttle-closer. bar P is closing the shuttlecover at, I arrange a guard 'i, Fig. 2, at the right of the bobbin-receivin g table 0 in such position that said guard will close the front end of the shuttle-holder B while its cover is being closed. This guard or guard-arm t" may be conveniently secured upon the vertical abutment-arm h, Fig. 12, hereinbefore referred to.

A vertical spindle w is stepped to oscillate in a step son the base of the machine-frame. This step has the form of 'a sleeve whose upper face 3 is cam-shaped, the spindle in carrying a sleeve. 3 whose lower face has a corresponding eam-face 5 Fig. 1. These camfaces sf 5- are of such configuration that when the spindle in oscillates in one di rectiont'. e.. from right to left-the said spindle is raised and returns to its normal position, Fig.- 1, when oscillated in an opposite direction. The spindle w! has secured thereto a radial arm 8 to which is pivoted one end of a connecting-rod 5 whose opposite end is pivoted on the pivot-pin of lever m to which is also pivoted, as hereinbefore described, the pawl-arm m'fl'that imparts the step-by-stcp rotation to the bobbin-carrier M, (see Figs. 1 and 2,) said lever m being, as stated, actuated by'the cam e.

. To the radial arm at on the upper end of the spindle w is secured the lower clamp-arm of the thread-holder T, which latter consists of said lower and of an upper clamparm i the outer ends t t of which are bent at right angles and constitute the nipping-jaws of the The outer end of the upper clamparm 25 is prolonged, bent downwardly, and has a second arm or projection tat right angles to said prolongation and lying in the plane of the nip of the nipping-jaws t t of the thread-holder T, as shown in Fig. 23. The aforementioned arm '1. has a clamp-opener in the form of a double-wedge or lozenge-shaped projection t Fig. 15), facing the nip of the jaws t t of holder T, and close to the inner face of the-jaw t is secured an arm t acting as a thread-guide. The lower arm i of holder T, as above stated, is secured to a radial arm 4 on the upper end of the spindlew and said arm has perforated lugs orears 6 secured thereto, in which is pivoted the upper arm i the tail of which in rear of its pivot is bent upwardly, so that said tail lies in a higher plane thanthe remainder of the arm, this to accommodate between said tail and the: tail of arm i a spring 25 which acts 'to hold the nipping-jaws closed, Fig. 21. On one side,at the rear end of the lower arm 15, is pivoted a latch 25 whose .bent upper portion overhangs the notched tail of arm t of holder T and has on its under face a convex boss fitting one or the other of two concave recesses in said tail of the arm 79, Fig; 21.

IIO

On the vertical arm of a bracket, which may conveniently be secured to the rear one of the two guide-rails H Fig. 21, is secured an abutmentplate above the threadholder T, said plate having two down wardly-projectin g abutments i and respectively, so arranged as that when the holder T swings in either direction the latch t contacts with one or the other of said abutments and is thereby shifted from one into the otherof the two recesses in the tail of arm t of said holder.

After the bobbin has been pushed into the shuttle in its holder 13, the thread-clamp K having been swung out to the position shown in Fig. 19, holding the thread end while the sh uttle-cover is being closed down or has been closed down, the spindle w is oscillated and at the same time raised to bring the threadholder T into the plane of the nip of the thread-clamp K, and said holder is swung forward, the nipping-jaws t t of said holder '1 being open, the latch i having been shifted into the rear recess in the tail of jaw i. As the thread-holder T swings into operative position the thread held by clamp K passes between the nipping-jaws of said holder at the same time the clamp-opener t on projection 75 of the arm i passes between the projections and It on the jaws of the threadclamp K, thereby spreading said jaws apart, said jaws closing again as soon as the opener has cleared said projections. As the jaws of the thread-clamp K are opened the latch 15 comes in contact with the forward abutment t" on abutment-plate If thereby shifting said latch from the rear notch or recess to the forward one in the upper arm i of holder T, thereby closing its nipping-jaws upon the bobbin-thread under the action of the spring 15 At the same time the thread-guide t is in contact with the like guide f on the pushbar E, thus insuring the proper guiding of the thread end into the thread-slot (Z in the cover d of the shuttle, Fig. 26. The guidearm f prevents the thread from slipping back into the recess d in the shuttle-cover, while the guidearm t prevents the thread from slipping from between the nipping-jaws t t of the thread-holder T, as more clearly shown in Fig. 26. The shaft 10 is now oscillated in an opposite directioni'. e., from left to rightand lowered so that the bobbinthread will be in the plane of the tensionspring 61 on the shuttle-cover dand in the plane of the thread-guide b on the upper face and at the rear end of the hinged part b of the shuttle-holder B, the thread-holder T swinging back. opener 25 again passes between the projections k and 70 on the jaws of the threadclamp K, again opening the same, releasing the thread therefrom and drawing it first under the tension-spring d and then under said thread-guide, Fig. 27, after which the latch 6 comes in contact with the rear abutment t on abutment-plate t whereby said latch is In this movement its clamprecess in the tail of the upper thread-holder arm i which arm is thereby moved away from arm 1/ against the stress of spring at, thus releasing the bobbin-thread; but before this takes place and while the bobbin-thread is held taut by the holder T a threading-hook Gr passes through the opening g in the hinged part b of the shuttle-holder B, through the threadeye (Z in the left wall of the shuttle, and through the space (1- between the sh uttlecover and the inner wall of said hinged part b of the shuttle-holder B to the left of the bobbin-thread, said hook immediately receding, at which moment the thread-holder T releases the thread, thereby drawing said thread from under clip b and threading the same through the thread -eye (1 of the shuttle, Fig. 29.

The threading-hook G consists of a bellcrank lever whose arm 9' is pivoted at g to a lug on the under side of the top plate or table of the machineframe, said lever-arm being also pivoted to one end of a connecting-rod g, whose opposite end is pivoted to a rock-lever g on shaft 1.0 which lever carries a roller g held in contact by a spring Z) with a cam c on cam-shaft to. To the upper end of the arcuate or. segmental arm 9 of the bell-crank lever is secured the threading-hook G. (See Figs. 1, 28, and 29.) .Iinmediately after the threading-hook G has moved back into its normal position below the table of the machine, Fig. 1, the slides B and 0 move to the left and right, respectively.

In order to insure the perfect closure of the shuttlethat is, to insure the locking of the cover in the lock-notch usually providedl employ an auxiliary closer, consisting of an eccentric, cam, or radial arm ion a pin Z, that is revoluble in a transverse bearing formed in the enlarged forked head of lever h, in which is carried the shuttle-opener H, said auxiliary closer being arranged on the left of said sh uttle-opener, Fig. 13. A spring Z secured to the radial arm Z and to the lever 7t, tends to hold the arm in a normal down position, Figs. 14 and 30.

As the slide B moves back from right to left and as the shuttle-holder B is moving under the auxiliary closer the lever 72 is depressed by its cam 6 thereby pressing down the auxiliary closerZ onto the shuttle-cover d and insuring its being locked to the shuttle.

The object of holding the auxiliary closer in its operative position yieldingly is to enable the shuttle-holder B to move from under it should the lever h not be lifted in time to move said closer out of the path of said holder. 1

By means of the mechanisms described the shuttles after leaving the auxiliary closerl are ready for use.

As the carrier-slide B and shuttle-holder B continue their movement to the left and when they reach a point where the longitudinal axis of the shuttle lies in line with the shutshifted from the rear recess into the forward 1 tle-ejector R, or substantially so, the movement of the slide is arrested for a sufficient time for the ejector to eject the shuttle from its holder into a suitable receptacle and move back again into its normal position.

The ejector-rod R is guided in a suitable guide Figs. 1, 2, and 31, which mayconveniently be secured to the rear one of the guiderails B the rear end of said rod being pivoted to a rock-leverr on longitudinal shaft 10 The lever r carries a roller r, held in contact with its actuating-cam e on the longitudinal camshaft to. Just before the ejector-rod R is moved forward to eject the shuttle the cam 11 on the rear end of the shuttle-holder pintle 71 comes in contact with the left downwardlyprojecting curved arm 0 of the lever 0 held in position by said ejector-rod, as hereinbefore described, thereby turning the pintle b to move the cam 11* from under the shuttle, and as this takes place the roller b? on lever 12 is moving to the highest point of the curved inclined track on plate b on the front face of the forward one of the guide-rails B thus opening the shuttle-holder. At this moment the slide B remains stationary and the shuttle-ejector R moves forward to eject the shuttle from said holder and immediately recedes again, the slide B continuing its motion to the left until the open shuttle-holder B again lies under the delivery end of the feed-trough, at which time the right-hand abutment a on said slide moves the shuttle-ejector A into the trough A to eject another shuttle therefrom, said ejector having been retracted from the trough by the action on the radial arm a on spindle a of the left-hand abutment a about the time when the slide B reached the limit of its movement toward the right or the receiving-table o.

As shown in Figs. 1 and 2, all of the principal actuating mechanisms are operated from the continuously-revolving transverse main cam-shaft w',to which-the motive power is applied, and the rotation of said shaft is transmitted through a bevel-gear 2 on said shaft to the longitudinal cam-shaft 20 through the bevel-gears thereon, there being only three other shafts on which the actuating-levers are mounted namely, the cross shaft 1.0 above the top of the machine, the like shaft 10 near the base of the machine, both shafts parallel with the main cam-shaft w, and the longitudinal shaft 10 parallel with and below the cam-shaft n1 Having now described my invention, what I claim as new therein, and desire to secure by Letters Patent, is
